Block YT and FB to all, except specific IPs

RouterOS Beginner Basics

Hello,

I’m new at the forum and in MikroTik routing.

I follow some tutorials on the net and I blocked youtube and Facebook to all IPs in my LAN (about 100 IP addresses).

Now, I want to enable those sites to specific IPs (only 3-4) and have problems to do that.

My MikroTik is RouterBOARD 750 and I use layer7protocol (^.+(facebook.com|youtube.com).*$) with action drop for blocking, and for enable action accept with specific ip in Src. Address, and that block sites to all clients, with no exceptions.

Thank you for your help
